Short summary

This study is intended to provide reference information regarding quantitative estimation of regional contributions and model uncertainty in meteorology simulations and emissions inventories. Simulated PM concentration is sensitive to meteorology, but estimated contributions are mostly robust. Regional contributions are also found to be sensitive to the choice of emissions inventories. The modeled results should be considered with caution when interpreted for emission regulation policy making.
